soc/ipq806x : Add CONFIG_TTB_BUFFER for the soc.

Define a base address for page table entries. Place it 64KB below the
    bootblock loading address.

BUG=chrome-os-partner:28467
    TEST=verified that the page tables are being populated at this
         address. Also observed that the SPI driver takes 900 ns to
         process a byte as opposed to 1.5 us in case caching is not
         enabled.
